MANACLE Specification of Letters Patent. Application filed March 28,1907. Serial No. 365,178.

Patented April 28, 1908.

To all whom it may concern:

Be it known that I, BARNARD L. WARD,'a

. citizen of the United States, residing at ttumwa, in the county ofVlapelloA and State of Iowa, have invented certain new and use-y fulImprovements iny Manacles; and I' do declare the following to be a full,clear, and exact description o? A p will enable others skilled in theart to which it appertains to-make and use the same, reference being hadto the accompanying draw` ings, and to the letters and iigures ofreference marked thereon, which form a part of this specification.l y

My present invention relates to manacles, and more particularly to animproved means for locking and releasing the clamp members of such adevice; this invention being an improvement on the device shown inLetters Patent No. 778,761, issued December 27, 1904, to Axel L. Nelson,the entire right to which invention 'and Letters Patent are now owned byme.

The Vobject of my invention is to provide a manacle of the constructionshown in the above mentioned patent, in which the clampv members areautomatically locked when applied to the wrist, but in vwhich thelocking parts are n ot accessible to one held thereby, although readilyoperated by the custodian.

The improved structure is illustrated in.'

the accom anying drawings, in which,-

Figure is a view in side elevation of a Amanacle bearing myimprovements. Fig. II is an end view of same. Fig. III is a view inlongitudinal section Aon the line III-III, Fig. II. Fig. IV is atransverse sectional view on the line IIL-IV, Fig. I.

The numerals 1 represent the clamp members which are curved as shown,and provided at one end with the reversely bowed shank portions 2,having the arcuate slots 3.

4 is the head portion having the grip members5, and a bifurcated neck,the'arms 6 of which are slotted at 7, and embrace the clamp memberShanks. Projecting through a channel 4: in the head-4 is a stem 8, theinner end. of which extends' between shanks 2 and is provided with aslot 9, while one of its edges is rovided with ratchet teeth 10.

Xtending through the neck arms at about their longitudinal center, andalso through perforations in the ends of Shanks A2l and through the slotin stem 8 is a pivot pin 11,

the invention, such as.

which anchors the clamp members to the head, and over which the stem isadapted to travel.

Extending through the slots 7 in the head neck arms, through. thearcuate slots in the clamp member shanks, and through a perforation inthe end of stem 8 is a loose pin 12 adapted to travel in said slots, butprovided with the keeperheads 18 to prevent its lateral displacement. p

Projecting through, and pivoted in a re -cess 14 in head 4 whichcommunicates with thechanneli is a lever 15, the lower end of which isprovided with teeth 1.6 adapted for engagement with the teeth 10 on stem8, and at its outer end with the thumb piece 17.

18 is a hat spring rigidly secured to the outer end of lever 15 yandbearing against stem 8 in a manner to yieldingly retain the upper end ofthe lever away` from the stem and the lower end thereof inwardly withits teeth in engagement with the teeth on said stem.

19is a seat sunk into the head around the stem channel and 20 is acompression spring resting in vsaid seat and surrounding'stem 8,

`with its upper end bearing against a button 21'on the outer end of saidstem.

In use, the upper end of the catch lever is pressed inwardly to rock itslower toothed end out of engagement with the stem ratchet, when thecompression spring 20 forces the stem outwardly by its tension againstbutton 21, thereby drawing the loose pin 12 out- Wardly and causing theclamp members to spread during the travel ofthe pin through the arcuateslots in the clamp member Shanks. By` grasping the handle grips by thelingers, with the button in the palm, and closing th hand, the stem willbe forced inwardly, forcing the loose pin through the arcuate slots inthe clamp member Shanks, and drawin the clamp members together.- Thecatch Ie being free, the lower toothed end thereof is held in yieldingcontact with the ratchet teeth tions projecting laterally from saidhead,

yoke arms projecting from said head intermediate said handle portions,clamp arms carried by said yoke arms, an actuating stem projectingthrough said stem channel and connectedJ with said clamp members, acatch lever pivoted to said head and projecting through said leverrecess, a stem locking member on one of said lever arms, an operatinghead on the opposite lever arm, the latter located above said handleportions, and means for normally retaining said locking member inengagement With said stem.

2. A manacle comprising a head having a lever recess, a neck projectingfrom said head and provided with a stem channel, and conimunicating withthe recess in said head, clamp members carried by said neck, anactuating stem extending through said channel and having a connectionWith the clamp members, ratchet teeth on said stem, and a catch leverpivoted in said recess and normally held in yielding locking engagementwith said stem.

In testimony whereof I affix my signature in presence of-two witnesses.

BARNARD L. WARD.
